log10(3F)                                               log10(3F)



NAME
     log10, alog10, dlog10, clog10 - Fortran common logarithm
     intrinsic function

SYNOPSIS
     real r1, r2
     double precision dp1, dp2
     complex cx1, cx2

     r2 = alog10(r1)
     r2 = log10(r1)

     dp2 = dlog10(dp1)
     dp2 = log10(dp1)

     cx2 = clog10(cx1)
     cx2 = log10(cx1)

DESCRIPTION
     alog10 returns the real common logarithm of its real argu-
     ment.  dlog10 returns the double-precision common logarithm
     of its double-precision argument.  clog10 returns the com-
     plex common logarithm of its complex argument.  The generic
     function log10 becomes a call to alog10, dlog10, or clog10
     depending on the type of its argument.

SEE ALSO
     exp(3M), matherr(3M).
